引入了最佳修正短时对数谱估计，能在信号存在的不确定性下最小化语音信号对数谱的均方误差。
We introduce an optimally-modified log spectral amplitude estimator, which minimizes the mean-square error of the log spectra for speech signals under signal presence uncertainty.
位场信号的径向平均对数振幅谱可以由多条斜率不同的直线段拟合，直线的斜率即为相应的等效层的深度。
The radially averaged log amplitude spectrum of potential field can be modeled by lines with different slopes, which are the depths of the corresponding equivalent source layers.
如果将能谱实验数据的对数拟合成直线以求得粒子温度，则最好对温度误差的平方和极小化。
However, if a straight line is fitted for logarithmic spectrum data to give the particle temperature, it is better to minimize the temperature square error sum.
